The kernel configuration between the two machines was identical. I looked at
what modules were getting loaded...they should've been the same, but the
"problem child" wasn't loading the saa7134 module properly. Adding these
module-load rules (cribbed from another system that used to be my backend...and
might be again; see below) fixed it:
add above nxt200x ivtv
add above saa7134 saa7134-dvb
With that in place, it found the channels without any problem.
(And now for something completely different, I think this current system may
end up being a demonstration why VIA-chipset motherboards are to be avoided for
MythTV use. It's an ECS KV2 Extreme, which used the VIA K8T800 Pro chipset.
I'm getting DMA errors from the built-in FireWire after less than an hour of
uptime. I tried adding in a PCI FireWire card, but then the A180 disappeared
(didn't even show up in the list of devices at POST). Pulling the FireWire
card let the A180 show up again. I might let it run overnight and see if it'll
run right now that the A180 is properly loaded, but if it keeps acting up, I
suspect I'll end up making my Core 2 Duo rig (an E6300 on a Gigabyte P945-S3)
my dedicated backend and make one of my Athlon 64s (probably the 3700 on an
Abit KN8) a dedicated frontend. Of course, if Fry's has anything interesting
planned for Black Friday, that's another option. :-) )
